Hi everyone, it's my first time here and I hope I'm posting this in the right section.
We are a small film preservation studio and our main film scanner is a Cintel with optional 16mm gate and KeyKode audio reader. We love working with Cintel and it delivers great results when scanning 35mm film.
However, scanning "some" 16mm films turns into a challenge, and sometimes outright impossible. The problem we're experiencing is stabilization. I've done countless experiments with various settings, X-Y stabilization on-off, audio, no-audio, HDR on-off, etc.
I've updated the Cintel software and firmware, including KeyKode accessory update to the latest versions. I'm now running Cintel 6.0 software and the latest beta 02 of DaVinci Resolve Studio. Upon seeing on the release notes that Cintel 6.0 software would improve 16mm stabilization, I was excited but unfortunately nothing changed for us.
I've narrowed down the problem to perforation detection. Perforations on films with a transparent base can't be easily detected by Cintel and therefore can't be stabilized. Frames jump all over the place. Just to confirm, I did some tests by simply painting the perforation side with a black marker, creating a higher contrast between perforations and actual film made Cintel easily detect them and stabilize the frames. However it's of course not ideal nor feasable to do this to whole film. I'm really hoping someone from support would shed some light on this issue because a large portion of our library consists of these kind of 16mm film prints.
I'm adding two frames with and without perforation painting. You'll see that when painted, Cintel can stabilize the frame in the center.
Thanks in advance to anyone.
